Nature Note: the Marbled Salamander
By Joe Settles

It’s a nasty fall day – its windy, spitting rain, and the leaves are falling off
the trees. Instead of grabbing a book and a warm spot - grab a sweatshirt, put
on an old pair of boots, and head out hunting for marbled salamanders (Ambystoma
opacum).
Nothing gets a marbled salamanders juices flowing like fall weather. The males
and females move to woodland ponds on rainy nights in September and October. The
male then puts on the old charm, and breeding occurs on land near the ponds. The
female deposits 70 – 150 eggs in a depression near the waters edge. The female
will guard the eggs until autumn rains fill up the pond and cover the eggs with
water. The eggs hatch and the larval salamanders spend the winter in the pond
feeding on a variety of little critters. Metamorphosis occurs around mid-May to
early June, when the little marble salamanders make their way back to the forest
floor.
Marbled salamanders get their name from their unique coloration. They are
primarily black with whitish/grayish markings on the back. Sexes can be
determined during the breeding season by coloration. Males have bright, white
markings and the females have grayish markings. Marbled salamanders can be found
statewide in wooded habitats. Look around the edges of woodland ponds under logs
or in the leaf litter in September or October, and you may find one of these
awesome critters. Good luck!
